Abstract
The invention discloses a rubber-synthesized sealing gasket material. The rubber-synthesized sealing gasket material is characterized by comprising the following raw materials in parts by weight: 55-60 parts of hydrogenated nitrile-butadiene rubber, 24-28 parts of silicone rubber, 1-2 parts of sulfur, 3-4 parts of zinc oxide, 4-7 parts of decabromodiphenyl oxide, 3-4 parts of diantimony trioxide, 4-5 parts of zinc borate, 3-6 parts of accelerator BZ, 1-2 parts of calcium stearate, 4-5 parts of octyl epoxy stearate, 3-4 parts of epoxidized triglyceride, 2-4 parts of ferrocene, 18-22 parts of white carbon black, 30-35 parts of N330 carbon black and 10-12 parts of modified attapulgite. According to the rubber-synthesized sealing gasket material, the technological property of rubber can be improved due to the addition of the modified attapulgite, and the toxic and side effects and environmental pollution can be reduced due to the use of environment-friendly compounding agents; the material is good in elasticity, has low compression deformation, is wear-resistant, anti-aging, good in sealing property, simple in technology, low in cost and suitable for industrial production.
